head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Practiced Mastery
A looter shooter where build optimization gates raid and seasonal content.

Execution · Practiced Mastery
40k co-op horde shooter with class builds.
Destiny 2 leans Optimization (Practiced Mastery); Warhammer 40,000: Darktide leans Execution (Practiced Mastery).
Warhammer 40,000: Darktide leans a little harder on execution, though the gap is small.
Destiny 2
Gunplay matters but raids forgive mechanics.
Warhammer 40,000: Darktide
Melee-gunplay weaving under horde pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Destiny 2
PvE is scripted; Crucible has light adaptation.
Warhammer 40,000: Darktide
Scripted specials, not adaptive opponents
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Destiny 2
Loot drops and rolls drive the chase.
Warhammer 40,000: Darktide
Director spawns and weapon rolls vary
Destiny 2 leans a little harder on optimization, though the gap is small.
Destiny 2
Build crafting, mods, and damage rotations dominate.
Warhammer 40,000: Darktide
Talent trees and breakpoints heavily solved
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
